Abstract
The application provides a method and device for adjusting a permanent magnet motor, an equipment, and a storage medium. The method includes the following operations. An electronic equipment acquires a counter electromotive force (CEMF) parameter, information of an electromagnetic structure of a permanent magnet motor to be adjusted and a minimum impedance value of any short-circuited coil of the permanent magnet motor to be adjusted, to determine an operational time of the short-circuited coil. The electronic equipment further judges, according to the operational time of the short-circuited coil, whether an adjustment instruction is required to be transmitted to a production equipment. When the operational time is inconsistent with a preset time, the electronic equipment transmits the adjustment instruction to the production equipment. The production equipment adjusts, according to the adjustment instruction, the electromagnetic structure of the permanent magnet motor to be adjusted. Through the method of the application, a rail transit vehicle may keep running for the preset time safely after an inter-turn short circuit failure occurs to the permanent magnet motor, and the operat…
